LTDC-X3 2-Channel LiDAR Time-to-Digital Converter LTDC-X3 datasheet Revision: 2 Release Date: 2025-04-09 Document Status: Production CONTENTS PAGE LTDC-X3 is a high-performance 2-channel time-to-digital converter specifically designed for single-beam LIDAR systems. It has a separate START channel, two STOP channels, measures up to 8 pulses on rising and/or falling edges, has a pulse-pair resolution as low as 5 ns, a typical rms resolution of 20 ps and a range up to 16 µs. It integrates a start pulse generator for generation of trigger signals to an external laser diode driver. Equipped with a quad SPI interface, the data rate can be as high as 50MHz / 200MBPS. It comes in a 4x4 QFN32 package and works in the industrial temperature range.
